During their work on the siyuan-note/siyuan repository, Blumia focused on enhancing the application's user interface by resolving a window controls overlay issue that previously obscured toolbar buttons. By carefully adjusting CSS and SCSS layout rules, Blumia ensured that toolbar elements remained accessible across different platforms, directly improving usability and reducing user friction. Their approach emphasized UI/UX design principles, prioritizing a clean and consistent interface. Although the period covered only one month and involved a single bug fix rather than new features, the work demonstrated attention to cross-platform compatibility and contributed to the overall stability of the front end.
